5V external battery pack
« on: February 08, 2007, 11:29:23 PM »
Can someone recommend a stealthable high capacity 5V external battery pack? Can be a fixed voltage battery - don't mind. Thanks.

i can make you a custom cable that drops the voltage from any feed higher than 7.6v to 5v.

to eliminate a 2nd battery, this is a good option.  especialy if your main battery has plenty of juice.

I guess it depends what you define as high capacity and what you want to use it for.  This is the battery I use with my MT:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=190080253476

I'm pretty sure I got it from the same seller.  Or do a search on ebay on "external ipod battery" and get one like it.  This one is 2200mAhr, which should allow you to run a MT for 6-8hrs. (including some support from the internal MT battery).  You can also get 3200mAhr batteries of the same type and form factor from other sellers.

This battery actually puts out 5.5v, but it works fine with the MT and I've done some short tests with the H120 and it seemed to work.  I don't know about using it with the finnicky JB3.  As to size, pretty easy to stealth with I'd imagine -- about the same footprint as a MT and about half as thick.

I run my JB3 with a PP-99 LiOn pack and it works great. They run about $30. Google it.

Don't seem to find the PP-99 LiOn pack when googled..

Don't need one with a USB plug but with a normal mini cylinder type (usual) plug.

Also, 2200mAhr is equivelent to having 4X AA NiMH batteries at 550mAh each? If so it doesn't seem a lot.

At the moment I have this Power runner PR32XX model:

http://datamind.co.uk/merchant/acon_Mod_2_Introduction.pdf

Set at 5V, the capacity is 7.2Ah.

Was looking for something similar in capacity but more stealthable (smaller).

Anyone know if there is anything better than my current battery?

QFT.  Digital Concepts PP-99.
(switchable voltages)

I have been using one for over a year now and it runs the JB3 for well over 3 hours.  I found a second one recently on Amazon through a 3rd party for about half of what I paid for the first one I bought.  The PP-99 has been discontinued so they are hard to find.  I would keep looking.

does the PP-99 come with various tips?
i can't seem to find any mAH numbers for this pack. can a user chime in on this one? thanks!

Yes, it does come with tips.  I think that the mAh's may be somewhere deep in the remote power board.  Maybe a search for pp-99

I wanna say it's 5400, but I'll look when I get home.

Yep, in the scheme of things, 2200mAhr is not all that large of a capacity, which is why I was wondering what you wanted to use it for.  2200 does not equal 4x 550mahr AA batteries, at least as we usually use them.  Most equipment we use will have the 4AAs wired in parallel to provide 6v (or 4.8v with NiMH), so the 2200mah pack would be equivalent to using 4AA's that are 2200mah each wired in parallel.

I also use the Dig concepts PP-99.  They are now discontinued, so they are harder to find.  I thought they were around 4000mah to 4500mah, but don't know for sure.  They are about 2-3x as large as the pack I linked above, but it is a nice powerpack and really not too large at all. 

So it all depends on what you're trying to do and what you consider stealthable.  Which makes me curious -- what are you trying to run and for how long?  The power draw of the H120, R09, MT, JB3, etc. isn't all that much, so a 2200mah pack should give at least 5-6hrs of runtime -- which is far more time than I ever like to do stealthing. :P

Thanks for your replies...I was planning to power my MR-1 recorder which needs 5V to power. Without external power it only runs for about 2 hrs using the internal battery.

This link shows a battery with capacity 3600mAh (13.3Wh).

http://www.batterygeek.net/product_p/blk_mobile_power_pack.htm

Does it mean it is equivalent to 4X AA batteries each with capacity 3600mAh in parallel??

This looks like a high capacity stealthable battery...
